Small spray dryer pharmaceutical Industry
The entire operation of the spray dryer is airtight and suitable for clean production areas. Because the spray drying operation is carried out in a closed tower, cross-contamination and dust flying are avoided, and it is suitable for the production of bulk drugs in the pharmaceutical industry, especially the production of sterile bulk drugs. .
The working principle of spray drying:
Spray drying can spray the slurry in the form of solution, emulsion, suspension, etc. into fine droplets in hot air. During the falling process, the water is evaporated to become a powder or granular product. Hot air is introduced at the top of the drying tower, and the slurry is sent to the top of the tower by the liquid pump at the same time, and sprayed into mist-like droplets through the atomizer. The surface area of the droplet group increases, and the moisture quickly evaporates after contact with the high-temperature hot air. It becomes a dry product in a very short time and is discharged from the bottom of the tower. Among them, the temperature of the hot air drops rapidly after contact with the liquid droplets, which causes the humidity to increase. It is drawn out by the exhaust fan as hot and humid exhaust gas, and the fine powder entrained in the exhaust gas is recovered by a separation device.
Advantages of spray drying:
The system adopts real-time adjustment PID temperature control technology to make the temperature control of the whole temperature zone accurate.
High-efficiency volute cyclone separator for material recovery.
Easy to clean, assembly and disassembly are very simple.
The drying chamber has a diameter of 1m and a high-quality mirror surface design to reduce the phenomenon of sticky materials.
The spray drying process is carried out in a pollution-free and stable environment.
18kw high power heating, faster heating speed.
The bipolar spiral hot air distributor makes the hot air more uniform.
The high-efficiency volute cyclone separator is used for material recovery, and the recovery speed is faster.
The cooling water pipe and circulating water cool the centrifugal pump motor. It is necessary to ensure that there is circulating cooling water during operation.
The components of the whole machine are integrally formed, all 304 stainless steel, anti-corrosion and easy to clean.
The whole machine has low operating noise, less than 50 decibels, and it is not noisy to use in the laboratory.
